Abstract
The invention discloses a mold suitable for the production of a supplementary restraint system cover. The mold comprises an upper mold, a lower mold and a cavity located between the upper mold and the lower mold, wherein the upper mold is sequentially provided with an upper fixed plate, a hot runner manifold and a cavity plate from top to bottom, and a cavity insert is arranged in the cavity plate; and the lower mold is sequentially provided with an oil hydraulic cylinder, a lower fixed plate and a core plate from bottom to top, the lower fixed plate is provided with a cooling water pipe, and the core plate is provided with a core insert, a containing space is formed between the lower fixed plate and the core plate, and the periphery of the containing space is supported through mold legs, and the containing space is internally provided with a support pillar, an ejector pin plate guide pillar, an ejector pin plate, an ejector pin and an ejector rod. The mold has the beneficial effects that after a cavity is moved away, the ejector rod is outwards pushed out by automatic reset elastic force of an elastic part so as to realize the one-time ejection, and meanwhile, a product deforms; the oil hydraulic cylinder is used for driving the ejector pin to be pushed out, so that the product is demolded, the demolding can be realized through two-times ejection, the mold is fast and high-efficiency, and the product does not need to be manually taken.
Description
Technical field
The present invention relates to a kind of mould, be specifically related to a kind of mould for the production of the air bag cover on vehicle steering.
Background technology
The mould of existing production safety air cell covering, master mold carries out the demoulding after removing, and at least needs three above actions, eject often and complicated operation, cause unitary mould volume larger, cost increases greatly, and after die sinking, need the manual pickup that coordinates, reduce production efficiency.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide one simple in structure, can complete the mould of the production safety air cell covering of the demoulding for twice.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
The mould that is applicable to production safety air cell covering, comprising: upper die and lower die and be positioned at die cavity between the two, and described patrix is from top to bottom provided with successively: upper mounted plate, hot runner manifold, caster, arrange a mother module core in described caster; Described counterdie is provided with from the bottom to top successively: oil hydraulic cylinder, be provided with cooling water pipe bottom plate, be provided with the male model plate of male die core, between described bottom plate and male model plate, form spatial accommodation and periphery supports by mould pin, in described spatial accommodation, be provided with support column, ejector retainner plate guide pillar, ejector retainner plate, thimble and push rod; Described push rod and thimble all stretch in die cavity, on push rod, cover has the elastic component that push rod is outwards ejected, the end of push rod is connected with a product cover core rod, thimble is subject to the driving of oil hydraulic cylinder and end to be positioned at product cover core rod, thereby on described product cover core rod, is formed with for thimble through the through-hole structure that makes product stripping.
Aforementioned caster is provided with guide pillar, on described male model plate, is formed with the guide frame coordinating with guide pillar.
Aforementioned push rod is a pair of, parallel arranged and through same push rod bundle piece.
Aforementioned elastic parts is helical spring.
Aforementioned thimble is two, is divided into the both sides of push rod.
Usefulness of the present invention is: mould of the present invention, and after master mold is removed, the elastic force that automatically resets of elastic component outwards ejects push rod, realizes and once ejecting, and product has distortion simultaneously; Oil hydraulic cylinder drives thimble to eject subsequently, makes product stripping, and eject and can realize the demoulding through twice, quickness and high efficiency, and without the product of manually taking.
Accompanying drawing explanation
